# Review a Pull Request in Electron with Atlas in 2026 > Atlas helps Electron developers review pull requests by going beyond the diff, using lsp to check ipcRenderer.invoke calls and ipcMain.handle pairings for security vulnerabilities. In 2026, Electron developers can review pull requests with Atlas by leveraging its deep understanding of the Electron security model, including contextIsolation and preload bridges, alongside real tools like npm, @playwright/test, and prettier to catch bugs a line-by-line diff would miss. ## Key takeaways - Atlas uses `lsp` to verify `ipcRenderer.invoke` and `ipcMain.handle` pairings in Electron for security. - Full file reads with Atlas's `read` tool provide crucial context beyond line-by-line Electron diffs. - Atlas integrates directly with Electron's `@playwright/test` runner and `prettier` formatter. - Permission-gated tool execution and unified diffs ensure safe Electron code reviews. - Atlas helps maintain Electron's `contextIsolation` and preload bridge security model. ## How Atlas Reviews Electron Pull Requests Beyond the Diff Atlas reviews Electron pull requests in 2026 by first fetching the branch and producing a raw diff using bash, then immediately moving beyond a simple line-by-line comparison. It reads full changed files, not just hunks, to provide a 360-degree view of modifications, ensuring no critical context is missed. When reviewing an Electron pull request, Atlas begins by using its `bash` tool to fetch the relevant branch and generate a raw diff, similar to `git diff origin/...`. However, Atlas's review process quickly moves past this initial diff. It employs the `read` tool to pull the full content of changed files, such as `main.js`, `preload.js`, and `renderer.js`, rather than just the modified hunks. This comprehensive file access allows Atlas to understand the surrounding code and identify potential issues that a limited diff view would obscure. For instance, a change in a main process file might impact a renderer process's `ipcRenderer.invoke` call, which a simple diff might not highlight. Atlas also uses `grep` to search for patterns like old constant names, stale copies, or feature flags that should have been updated but were overlooked, ensuring a thorough review of the entire Electron codebase. ## Ensuring Electron Security with Atlas's LSP and Context Awareness Atlas significantly enhances Electron application security reviews in 2026 by understanding the framework's unique contextIsolation and preload bridge model. It uses the lsp tool to specifically check for breaking changes in ipcRenderer.invoke calls paired with ipcMain.handle implementations, a critical step for preventing 0-day exploits. The Electron security model, built around the main/renderer split, `contextIsolation`, and preload bridges, is a core focus for Atlas during pull request reviews. Atlas leverages its `lsp` (Language Server Protocol) tool to perform `findReferences` operations on changed function signatures, particularly those related to inter-process communication (IPC). This means Atlas can trace `ipcRenderer.invoke` calls in the renderer process to their corresponding `ipcMain.handle` implementations in the main process. By doing so, it identifies if a change in one process inadvertently breaks the IPC contract or introduces a vulnerability, such as exposing a Node.js API directly to the renderer without `contextBridge.exposeInMainWorld` in the preload script. Atlas also helps confirm that `nodeIntegration` remains off, a fundamental security best practice for Electron applications. ## Automating Electron Test Execution and Code Formatting Atlas automates critical steps in Electron pull request review, including running tests and formatting code, saving developers valuable time in 2026. After reviewing the diff, Atlas can execute @playwright/test cases that drive the packaged app, ensuring new changes haven't introduced regressions, and then apply prettier formatting. A crucial part of any Electron pull request review is validating functionality and maintaining code style. Atlas streamlines these tasks by integrating directly with the Electron toolchain. Using its `bash` tool, Atlas can execute `@playwright/test` cases that are configured to drive the packaged Electron application. This ensures that new code changes haven't introduced regressions or unexpected behavior, especially in complex interactions between the main and renderer processes. Atlas will prompt for permission before running these tests. Following successful test execution, Atlas can then invoke `prettier` via `npm run format` (assuming a `format` script in `package.json`) to automatically apply consistent code formatting across the modified files. This guarantees that the codebase adheres to established style guidelines without manual intervention, freeing developers to focus on logic. ## Atlas's Permission-Gated Actions and Unified Diff Approval Every action Atlas takes during an Electron pull request review is permission-gated, providing developers with full control and transparency in 2026. Before running any tool, such as npm or prettier, Atlas consults allow, ask, or deny rules, and presents a unified diff for approval before writing any changes to the codebase. Developer control and safety are paramount when using an AI agent like Atlas for Electron pull request reviews. Atlas operates with a robust permission system, where every tool call - whether it's `npm`, `prettier`, or `lsp` - is gated against allow, ask, or deny rules configured by the user. This ensures that Atlas only performs actions explicitly permitted. Furthermore, Atlas drafts its review plan in a read-only plan agent, allowing developers to understand its intentions before any modifications are proposed. When Atlas suggests changes, it computes a unified diff for every file edit and surfaces it for explicit approval. This transparent process means no changes are written to your Electron codebase without your consent. Atlas also snapshots file changes as git patches, providing an easy mechanism to diff and roll back any approved edits if needed, offering an additional layer of safety. ## Steps 1. Fetch the Electron PR branch and generate the initial diff: `atlas bash git fetch origin && atlas bash git diff origin/...` 2. Read full changed Electron files (e.g., `main.js`, `preload.js`, `renderer.js`) for complete context: `atlas read ` 3. Check `ipcRenderer.invoke` and `ipcMain.handle` pairings for security and breaking changes using `lsp`: `atlas lsp findReferences ` 4. Grep for stale patterns, old constant names, or feature flags in Electron files: `atlas grep "oldConstantName" ` 5. Run `@playwright/test` cases to validate Electron app functionality and catch regressions: `atlas bash npm test -- --project=electron` (requires permission prompt) 6. Apply `prettier` formatting to ensure code style consistency across the Electron project: `atlas bash npm run format` (assuming `format` script in `package.json`) 7. Review Atlas's proposed changes via the unified diff and confirm `nodeIntegration` remains off in the Electron configuration. 8. Approve or roll back changes using Atlas's built-in git patch snapshots and commit the final review. ## FAQ ### How does Atlas check Electron security vulnerabilities in PRs?
